Identifying Duplicate Records

Jun 26, 2005

Be advised that I'm a complete novice with Access, and have used it only to view Excel files with more than 64,000 records. Any help would be appreciated.

I have an Excel file of 10,000 records entered by salesmen of possible prospects, with salesmen, prospect name, address fields. Some salespeople have entered the same prospect and address information; the only thing different in these records are the salesman name.

I know how to import the file into Access. But from this point, how do I construct a query and generate a report that shows me ONLY THE DUPLICATE RECORDS? We would like to use this report to identify the double entries and the salespeople so they can clean up the database. I know Access (I have Access 2003) can create this query, I don't have a clue on how to do it.

One hint: A post on another forum suggested " Make a group-by query (grouped on all fields except salesperson). Add a count field. Select if count >1. This should do the trick."

I'm sure this is the answer, but I don't know how to "make a group-by query", how to "add a field", etc. Like I said, I know how to import the data. That's it.

This is extremely frustrating to be this close to the answer and not know how to finish it. Any assistance would be appreciated. Thank you.

Identifying Updated Records

Oct 23, 2006

Hi

I have my table set up to add today's date as a "date last updated" field. this works for all new records but I need to flag instances where a user has amended any existing records, so that on a daily basis I can filter out anything new based on the "date last updated".

Any ideas how I can flag changes to existing records?

Apologies if this is a straight forward question I'm fairly new to Access

General :: Identifying In And Out Work Times Records

Feb 1, 2015

I have a table (Imported from Excel) with In and Out records.

Here are the problems I have:Each record has either In or Out data. I have an identifier to know which ones are In and which ones are Out

It might have some misses, either no In or no Out record for the specific work time. A worker can get in at the evening and get out at the morning of the next day. Might have more then one entrance/exit on the same date.

I want to have the record sorted so I'll have an In and Out on the same row (record) including holes for the missing ones.

Queries :: Mass Duplicate Main Records And Related Subform Records

May 29, 2014

In my simple database (attached), I need to mass duplicate Tasks and their Notes.

I have three tables: tbTasks (PK: Task_ID), tbNotes (PK: Note_ID), jtbTaskNotes (FKs: Task_ID and Note_ID). jtbTaskNotes is my many-to-many junction table that ties Tasks to Notes.

The main form (fmTasks), bound to tbTasks, has a subform (sbfm_TaskNotes) that displays notes associated with each Task. On themain form,you select which Tasks you want duplicated via a checkbox. The append query (quCopyTasks) will duplicate all tasks that have the checkbox checked. All good there. However, I can't figure out how to also duplicate each task's Notes.

I found Allen Browne's solution [URL] ....., but that only handles duplication of one record at a time, whereas I need to duplicate many records at a time (sometimes 10+ records). How do I go about duplicating multiple Tasks and their associated Notes?

Before you ask "why are you duplicating records?": There are times when tasks need to be re-accomplished and therefore need to have a new record. It's easier to duplicate records than it is to hand-jam everything again.

Qry Results Show Duplicate Records, Records Are Not Dup In Table.

Nov 16, 2004

I have built a qry that initially shows the correct information. For example.

tblContent has 289 records with a Type = Class.

I built a Query to select from tblContent Type = Class and I get 289 records. I add additional criteria of Progress <>"Not Scheduled", I then get 206 records. I then add additional criteria Last Name <>"Demo" And <>"Care" And <>"Support". This brings up 200 records, but the query appears to duplicate each record 3 times. I do not have 3 of the same types of records.

The SQL Statement is below

SELECT tblProfile.LoginName, tblProfile.FirstName, tblProfile.LastName, tblProfile.Organization, tblProfile.CostCenter, tblContent.Title, tblContent.Type, tblContent.Code, tblContent.[Date Assigned], tblContent.[Date Started], tblContent.[Last Accessed], tblContent.Progress, tblContent.[Date Completed]
FROM tblProfile INNER JOIN tblContent ON tblProfile.LoginName = tblContent.LoginName
WHERE (((tblProfile.LastName)<>"Demo" And (tblProfile.LastName)<>"Care" And (tblProfile.LastName)<>"Support") AND ((tblContent.Type)="Class") AND ((tblContent.Progress)<>"Not Scheduled"));

The qry is named qryPhysical Class. I have provided the link to view the database. Can you help me?

Duplicate Records

Oct 24, 2006

Hi

I have a table (which is populated by people filling in a form) which contains two fields:

Section
WeekCom (e.g. week commencing)

I want to make sure that the form will not allow someone to make a double entry. For example, if Sally goes in and says enters "Benefits" as the section and "WeekCom" as 15/10/06, and then Ben tries to do the same - the form will not allow Ben to enter it.

How do you do this please? The table does not have a primary key at the moment....is there any way of doing it without setting one of the fields as a primary key?

Thanks

Maria

Identifying The Active Form

Jan 17, 2006

Apologises if the answer is out there somewhere but I have searched to no avail.

I have a number of Forms which the user can jump around from one to the next. All the forms remain open with the form they are currently viewing showing on top. If they make a change on one particular form then when they return to a previously viewed form I want to disable or hide certain certain controls etc.

I know this would be simple to do on the on open command but as previously mentioned as I am not closing the forms after they are viewed, if the user returns to a previously opened form then this is not picked up.

Soooo, basically I'm after something like

When the user moves from one form to another already opened form for the new form to immediately know that it now has the focus and for it to do something along the lines of on open.

Any help will be appreciated

Random Duplicate Records

Feb 20, 2006

Hi Guys,

I hope someone can help with this. I have a table, "Blasthole Submission" which is populated by input in a form, using the code below:


Const MyTable As String = "Blasthole Submission"
Const MyField As String = "Sample Name"
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim intCounter As Double
Set db = CurrentDb
Set rs = db.OpenRecordset(MyTable)
For intCounter = Me.txtStartValue To Me.txtEndValue
rs.AddNew
rs.Fields(MyField) = "TP" & intCounter
rs.Fields("Submission #") = Me.SubNum
rs.Fields("Sample Type") = "Blasthole"
rs.Fields("XRF") = "True"
rs.Fields("LOI") = "True"
rs.Update
Next intCounter
rs.Close
db.Close
Set rs = Nothing
Set db = Nothing


What I am hoping to do is to place a random duplicate in the table, called, for example TP111152 DUP, approximately every 50th record. Is there any easy way of doing this?

Thanks in advance for your help!

How To Prevent Duplicate Records?

Jan 13, 2007

i am using a textbox in the main form to transfer the Yr/Mth into the table. (refer to qp.zip)

e.g: currently whenever i scroll ard the months control in the form, i will get duplicate Mth/Yr into the table. how do i prevent that from happening?

i only want to have updated data inside the Mth/Yr table instead of duplicated Mth/Yr

Public Sub PutInMonthlyRecords()

Dim sql As String
Dim Db As DAO.Database
Dim rs As DAO.Recordset
Dim f As Form
Dim MthYr As String

Set f = Forms!frmQpi

MthYr = f("txtMthYr")

sql = "SELECT * FROM [tblQpiMonthly] WHERE (([tblQpiMonthly].[Input MthYr] = 'MthYr' ));"

Set Db = CurrentDb()
Set rs = Db.OpenRecordset(sql)


If rs.RecordCount = 0 Then
If (f!txtTotalPF) = 0 Then
Exit Sub
End If

rs.AddNew
rs![Input MthYr] = f("txtMthYr")
rs![Monthly TotalPF] = f("txtTotalPF")
rs![Monthly Rejection] = f("txtTotalAvoid")

Count Duplicate Records

Mar 27, 2006

I have an order database using Access 2000, I need a report to list all agents that have ordered in the past year, how many times they ordered and sort by Office city.

I have
SELECT tblCustomers.Type, tblAgentList.AgentID, tblAgentList.LastName, tblAgentList.FirstName, tblAgentList.Agency, tblAgentList.AgencyCity, tblAgentList.DeliveryAddress, tblAgentList.DeliveryCity, tblAgentList.DeliveryState, tblAgentList.DeliveryPostalCode, tblAgentList.[AgentOffice#], tblCustomers.InspectionDate
FROM tblAgentList INNER JOIN tblCustomers ON tblAgentList.AgentID = tblCustomers.AgentID
GROUP BY tblCustomers.Type, tblAgentList.AgentID, tblAgentList.LastName, tblAgentList.FirstName, tblAgentList.Agency, tblAgentList.AgencyCity, tblAgentList.DeliveryAddress, tblAgentList.DeliveryCity, tblAgentList.DeliveryState, tblAgentList.DeliveryPostalCode, tblAgentList.[AgentOffice#], tblCustomers.InspectionDate, tblCustomers.[Job#]
HAVING (((tblCustomers.Type)="P") AND ((tblCustomers.InspectionDate)>[Enter starting Date:]))
ORDER BY tblAgentList.AgentID, tblAgentList.AgencyCity, tblAgentList.AgentID;

It list all agents sorting by AgentID, with a line for each order.
I would like to list each agent once with the number of times ordered, and then sort by AgentCity. Any help would be appreciated... Thanks in advance!:D

How To Stop Duplicate Records

May 2, 2006

I have two table. Deliveries Created (DC) and Goods Receipt (GR).

I have a query which links the two by PO number, PO Item, Unit code and Delivery quantity.

This works fine until one PO Number has more than one delivery quantity which is equal. For example.... The PO quantity is 4,000 but, because the units can only be shipped in quantities of 1000, there are four different entries in both the DC and the GR tables each with the same PO number, PO Item number, Unit code and delivery quantity (and shipped on the same date). This of course gives 16 results for the query using this PO number.

There is one unique field in the DC table this is the posting number field. I've tried grouping by this number and taking the First values from the GR table. This works OK in that it produces Four results but, two of the deliveries were received on Day 1 and two were received on Day 2. If I take First of GR date I get DAY 1 for all, If I take Max I get Day2 for all. What I need is the correct date.

I hope I have explained this OK.

And I hope you can help

Duplicate Records In Queries

May 10, 2006

I thought I had just about finished my DB but now Ive printed out and checked my reports I notice I have several records in different types of reports showing duplicate records. Iv'e gone back over the queries and there are one or two duplicates in several of my queries that I did not notice before because there are are only the odd one or two. No matter what I do I can't stop this happening. I think it must be something to do with the dates in my payment table. PaymentID is key field - foreign key is MemberID. One member can have several paymentID's a new one every year when membership renewed. The problem seems to be when the member has two payment dates in the same year. This shouldn't be anyway but the database has not been used properly with entry dates missing, written over of wrong dates etc. Ive tried to correct this but do not want to tamper with past payment date records. I already have 'select distinct' in my queries and have tried 'distinct row' which seems to return even more duplicate records. Im pulling my hair out over this there must be a way to return the records from members showing just 1 only of their very latest payment record/date. Im using this expression in the query.

LastPaid: (SELECT MAX(PaymentDate) FROM S_Payments_Table WHERE S_Payments_Table.MemberID =S_Members_Table.MemberID)

Finding Duplicate Records

Jun 19, 2006

Hello

I've had to export data from an old third party database to Access with the task of reporting on the data. I have a client table and work tables, one for each year going back to 1992. In the original database, the clients do not have a date of when they were set up. I need to find out how long clients have been with us, so I thought of going back through the work tables 2006 to 1992 and finding out where they first occurred, by looking for duplicate records in the tables. Is this a simple enough thing to do? The client table and work tables are linked through the field Client.

Thanks

Query For Duplicate Records

Jul 9, 2007

I am creating an ordering system which comprises of amongst others, these fields:

ID
OrderHdr
OrderLine

I want to ensure that if a user enters an ID, OrderHdr and OrderLine that this combination does not already exist elsewhere within the same table.

I have written a query like this:

COUNT OrderLineDetails.id, OrderLineDetails.orderno, OrderLineDetails.orderline
FROM OrderLineDetails
WHERE (((OrderLineDetails.id)=?) AND ((OrderLineDetails.orderno)=?) AND ((OrderLineDetails.orderline)<>?));

I will be replacing the "?" with the relevant form fields from the form, but how do I run the query and store the result in a variable and prevent the user from carrying on until they change any of the fields until there is no duplication.

-------&gt;&gt;&gt; Please Help On Filtering Out Duplicate Records.

Mar 14, 2008

Hi there,

I'd like to filter out so that the name only appear once base on LastOfDate.

Sample data in query

Customer_____Date__________Product
John_________02/02/2008_____A
John_________05/03/2007_____B
John_________03/06/2006_____A
Nick_________04/04/2006_____A
Nick_________04/04/2007_____B
James_______05/04/2008______A

So in the query, I just want to have John, Nick and James appear once with the LastOfDate.

The result should be
John_________02/02/2008_____A
Nick_________04/04/2007_____B
James_______05/04/2008______A

I included the db file which only perform LastOfDate and unique name, however since John has product A and B, it won't get rid of B.

SELECT DISTINCT query1.Name, Last(query1.Date) AS LastOfDate, query1.Product
FROM query1
GROUP BY query1.Name, query1.Product;

I just want one Name, LastOfDate and one product, regardless of A or B.

Thanks,
Isabel
